Pinnacle engineering enterprise manufactures surface grinder. These grinders are available with technical specifications like 450 x 150 mm table size manual machine to 1,000 x 300 mm table size hydraulic machine and 800 x 400 mm and gsh-8 jumbo with table size 1,000 x 500 mm are in hydraulic as well as nc/cnc version. The sumo series of machine have robust base structure and have internationally accepted fixed column design. The heavy box type column casting with honeycombed ribbing is rigidly clamped to heavy base casting with honeycombed ribbing is rigidly clamped to heavy base casting. The spindle housing supports cartridge type spindle unit and is fitted with super precision bearings grease packed with imported grease for long trouble free service. The table drive is hydraulic with soft table reversal device to facilitate smooth table reversal. The automatic electronic cross feed is variable from 0.5 to 6.0 mm at each table reversal with a facility of rapid power positioning and additional safety manual to auto interlocking device. An automatic lubrication system is provided in longitudinal as well as transverse guide way with separate controls to control the flow of lubrication oil. The machines are tested as per is test-chart. The surface grinding machines come with salient features like within 10µ flatness accuracy and 0.4 to 0.8 µra surface finish.
